Specification of Letters Patent. P n-tented Sept, 16,1913.-

lpplieati'cn filed Jifliv $1, 1968; Serial Ifo, 446,399.

To all toliom it may conce'm Be it known that I, Grouch B. Bassmr, a citizen of the United Stat s, r siding at Buffalo, in the county of Erie and State of New York, have inventeda new and useful Water-Meter, of which the following is a specification.

My invention relates principally to improvements in disk water meters but my improv'ements in the intermediate gearing and gear frame are applicable to any water meter using: intermediate gearing between the measuring device and theindicator; v

Theobjects of my invention are principa-IIy to improve the construction of the outside casing, disk chamber, disk and disk bearingsgear frame, intermediate gear and gear bearings, strainer and otherpartsin the construction of water meters for the purpose of reducing" the cost of manufacture, allowing the more ready assemblage, sepa- -ration and adjustment of parts, increasing the efiici'enc'y and durability, and giving other advantageous results, I attain these objects by the mechanism illustrated in the accompanying drawings in Which- Figure 1 is a vertical longitudinal section ofthe entire meter. Fig. 2 is a top view of the bottom half of the outside case containing the bottom half of the measurin chamber in which the disk is shown in a orizonta'l position for purposes of illustration; Fig. 3 is a side view of the measuring chamber, showing theports into and out of same and is cut away opposite the outlet ports to show the outlet ports in the cones and a section of the disk web and sliding block, the disk spindle being in a position 90 degrees from its position in Fig. 1, for purposes of illustration; Fig. 4 is a horizontal section of the gear frame and the intermediate gear pinion, Fig 5'shows an improved bearing for the intermediate gear over that shown in Fig. 1. v

Similar numerals refer to similar parts throughout the several Views. a

1 is the outside bottom case' of; the meter to which top outside case' 2' is fastened by bolts or screwspassing" through holes 3 in their meeting flanges 4' and 5:

6 is an indicator mounted in a circular notch' formed in top of top case 2" and ing, flange 11 whereby the two halves of the disk chamher are clamped together and also heid in seat 9 by'top outside case 2 and its meeting flange 5'.

is'a circular cylindrical strainer that is held eceentricaily around the outside of the measuring chamber by the eccentric circular projection 13 in bottom of outside case 1' and a corresponding eccentric circular projection- 14' on the under side of measuring chamber flange 11. a V

In thdisk chamber; is supported the nutating' measuri disk, the web 15 of which is ci mp'edbetween the two halves 16 and 17' of the central bearing ball which are securely held together by hollow tubularrivet 18' in which is removably mounted the disk controlling spindle 19' which is tightly pressed into the central hole in'tu'- buiar riv' et 18. Web 15 may be made of metal. l teretofore, the two halves of the disk ball; have been held together between a houlder on the upper part of' the disk spindle and a nut or screw on the lower part of same. As the disk ball is usually made of hard rubber, which has a much greater co'eficient of expansion and contraction than metal", due' to diiier'ences of temperature, the nut or screw has a tendeuc'y' f0 work loose, which is overcome by my tubul r rivet faste'ning;- After the parts of the disk are assembled and before the disk spindle is pressed into place, the disk may revolved by placing it on a lathe mandrel and tested to see that it is true, or the ball" and web may be machined after it is assembled by holding it in the same manner. The disk spindle being removable, may be replaced' when worn Without dist-urbingthe relative positions of the otherparts' of the disk.

Thero't'ative' thrust of the disk is received" by sliding block 20, which is fastened to the disk with a ball and socket joint 21. Sliding block 20, which may be made of a non-metallic substancesuch as hard rubber, has a fiat bearing surface against partition plate 22 upon which it slides up and down in the arc of a circle as the disk nutates. Heretofore, sliding blocks have been fastened to the disk so as to oscillate about an axis either parallel with the disk web or at right angles to it. In neither of these does the sliding block maintain a flat contact with the partition plate at all points of its path, which defect is overcome by my improved sliding block with a ball and socket flat bearing surface against the partition plate. Partition plate 22 extends into recesses formed in the inner surface of the conical walls of the disk chamber so as to provide an ample bearing surface for sliding block 20 when at the ends of its path.

There are two outlet ports, 23 formed in the conical wall of lower half 8, and 24 formed in the conical wall of upper half 10 of the disk chamber, adjacent to and on the same side of partition plate 22. On the other side of and adjacent to partition plate 22 is inlet port 25 formed in the spherical side wall of the disk chamber.

The submerged space between the outside walls of the disk chamber and the inside walls of the outside case is divided into three compartments. Inlet compartment 26 extends entirely around the spherical side walls of the disk chamber and contains cylindrical strainer 12. It also connects inlet spud 27 with inlet port 25. Outlet chamber 28 is located entirely below the measuring chamber and connects outlet port 23 with outlet spud 29 through outlet channel 30. Above the measuring chamber is located intermediate gear and outlet chamber 31, which contains the submerged intermediate gearing or reducing train and also connects outlet port 24 with outlet spud 29 through outlet channel 32.

Outlet port 23 will let any dirt pass out of the disk chamber that may settle in it, which otherwise might accumulate and block the disk, while outlet port 24 will let out any air that may be in the disk chamber and which might otherwise be entrapped in it and prevent the meter giving full measurement. The outlet ports are so placed as to also form the recesses which accommodate sliding block 20 at the ends of its path.

Formed integral with the gear frame is overhanging bearing arm 38 in which revolves the upper end of driving shaft 39,

on the lower end of which is crank arm 40 which contacts with and receives motion from disk spindle 19. Securely mounted on driving shaft 39 is driving pinion 41 which meshes with and drives intermediate gear wheel 42 which is securely mounted on intermediate gear pinion 43, which meshes with and drives stuffing box gear wheel 44 and its shaft 49. Intermediate toothed pinion 43 and its toothed gear 42 are loosely mounted on adjustable gear post 45 on which it turns. The upper end of gear post 45 receives the Weight of pinion 43 and its gear 42. The lower end of gear post 45 has a screw thread by which it is supported in bottom plate 34 and also by which its height may be adjusted to take up any wear that may occur on its upper end.

46 is a jam nut to hold gear'post 45 securely in place and prevent its turning after it has been adjusted to the proper height.

When it is desirable to reduce the friction of intermediate gear pinion 43 and its gear 42, I place a ball 50, on top of gear post 45, as shown in Fig. 5, making a very sensitive and easy running ball bearing at this point.

Clamping nut 51 securely holds supporting stud 37 and its gear frame in a hole formed in the top of outside case 2. On top of supporting stud 37 is the packing or stufiing box 52 through which stuffing box,

shaft 49 passes. On the top end of stuifing box shaft 49 is securely mounted meter change gear wheel 53 which meshes with and drives indicator change gear wheel 54 which is securely mounted on indicator spindle 55.

In operation, the water enters at inlet spud 27 thence passes through cylindrical strainer 12 and inlet compartment 26; thence through inlet port 25 into the measuring chamber causing the measuring disk to nutate; thence out ofthe measuring chamber through outlet ports 23 and 24 into outlet compartments 28 and 31; thence through channels 30 and 32 out of the meter through outlet spud 29. The motion of the nut ating disk is communicated to indicator 6 by the submerged intermediate gearing, stuffing box shaft 49, and change gears 53 and 54.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. In a disk water meter, the combination ate toothed pinion formed with a longitudinal central hole closed at the upper end mak-' ing an inelosed supporting bearing on the top end of said gear post and ball on which 5 it rotates in transmitting motion from said device to said indicator substantially as and for the purpose described.

In iwitness whereof I have hereunto set Witnesses:
